I'm not sure if the question you are asking is how to set the hostname of the server. If it is, then it will probably depend on which Linux distro you are using (RedHat, Mandrake, Suse, debian, etc).

For Redhat, edit the file "/etc/sysconfig/network" and change the HOSTNAME parameter to be what you want your computer to be called.

there is serveral files you will going to add those info depending what you need. the normal files are

/etc/hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.
192.168.0.1           servername.abc.com    servername
127.0.0.1               localhost.localdomain localhost

/etc/sysconfig/network

NETWORKING=yes
HOSTNAME=servername.abc.com
GATEWAY=192.168.0.254

and if you have the sendmail, in the /etc/mail/sendmail.cf will also need to put your domainname into it
